Abstract

Une pluralité de fibres de carbone (1) est recouverte d'une résine (2) électriquement non conductrice de sorte que les fibres de carbone individuelles ne soient pas mises en contact mutuel et afin de former un faisceau de fibres de carbone. Les pointes des fibres de carbone sont rentrées d'un côté du faisceau de fibres de carbone de manière à créér des orifices très fins (3) qui sont ouverts du côté externe. De plus, les pointes rentrées des fibres de carbone sont enrobées le cas échéant d'une membrane permsélective, d'une enzyme ou d'un micro-organisme, ou d'une substance (4) électrochimique catalytiquement active. Les micro-électrodes obtenues ont une faible sensibilité au débit, subissent une pollution moindre, et peuvent être utilisées en tant qu'électrodes pour la mesure d'oxygène dissous, pour la mesure de la concentration en ions, comme électrodes pour biocapteurs, ou électrodes de référence.
